Bounds on sterile neutrino parameters from reactor experiments~1

摘要

In this work, we present a realistic analysis of the potential of the present-day reactor experiments Double Chooz, Daya Bay and RENO for probing the existence of sterile neutrinos. We present exclusion regions for sterile oscillation parameters and find that these experimental set-ups give significant bounds on the parameter Θ_(ee) especially in the low sterile oscillation region 0:01 < ?m_(41)~2 < 0:05 eV~2. These bounds can add to our understanding of the sterile neutrino sector since there is still a tension in the allowed regions from difierent experiments for sterile parameters.
